Steve, 

Thanks, I'm beginning to get the picture now.  I'll have to get everything back together to see how to hook up the linkage to the throttle.

Mark,

 

I have been using the OMP from a separate reservoir for almost 300 hrs.  The check valves are connected to the intake between the air filter and the throttle body like they were in the car.  The control lever is connected to the throttle body control so it is full up at full throttle and full down at idle.  At altitude, if I do not close the throttle just to the point where it starts to decrease MAP, the two stroke oil will accumulate in the crankcase.  When operated this way, the oil consumption is just a little less than 1 oz per gallon of fuel.  Locking the control full open would deliver too much oil for my system.

Is anyone running an oil metering pump (OMP) that can help me figure out how the lines should be connected.  I'm planning on using the Mazda banjo fittings to hook up to the OMP, but what do I do with the check valves.  Do you connect the check valves to a vacuum source or just block them off?  Will the system work properly if I plug the check valves?  I plan on locking the lever in the full open position.  Will this work for a/c use?  I'll be using Richard Sohn's adapter with a 1 gallon reservoir filled with 2-stroke oil.
